Track Notes Turn by turn instructions & maps

Getting started
From the front of the 'Kalkari' centre, this walk heads gently downhill through the car park, keeping the Ku-ring-gai Chase Road to your left, to walk past the 'Kalkari Bush Discovery Track' map to the 'Birrawanna Track' sign at the far end of the car park. This walk now follows the 'Birrawanna Track' sign to the SW corner of the Kalkari enclosure fence and follows the fence for just shy of 400m to step down off a rock platform and continue along the fence for another 150m to the NW corner of the enclosure fence. Here the walk leaves the fence and follows the track as it gently undulates through the wooded forest following the occasional timber step for just over 350m to come to a clear four-way intersection where a sign points back to the 'Kalkari Visitor Centre'.
From the intersection this walk follows the 'Bobbin Head' arrow post east along the track as it almost immediately passes under a set of power lines. The track starts to wind downhill, down a number of timber steps for about 250m where the sandy track flattens out again to come to a three-way intersection marked with a 'Kalkari' sign point back up the hill.....
